Specification of Letters Patent.

Patented net. 9,1915.

Application filed-February 16, 1914'. SeriahNo. 818,956.

To all whom it may concern Be it known that I, ARTHUR W. NnLsoN,

a citizen of the United States, residing at l/Villiamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Sasl1-Supporters; and I- do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in: the artto which it appertains to make and use the same.

This invention relates to improvements in means for supporting window sash and the main object of the same is to devise an article of the character described which will obviate the necessity of employing; weights.

to retain the sash in raised position.

Tothis end, a second ob ect is to construct the device in such a manner that it will allow the window to be easily raised, but

will effectually retard its descent.

lVith the above objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is an inside elevation of a portion of a window sash and frame showing the a-pplication of my invention thereto; Figs. 2 and 3 are edge views of the opposite edges of the sash showing the location of parts thereon; Fig. 4 is a detail horizontal section on the line 4-4 of Fig. 1; Fig. 5 is a detail vertical section showing the manner of mounting the supporting rollers; and Fig. 6 is a side elevation of one of the attaching plates on an enlarged scale.

In the accompanying drawings, I have shown a window frame F comprising the usual sill S, parting strips P, and sash retaining strips .9 and a sash S which is slidably mounted within said frame and be tween the strips P and s in the usual manner. The opposite sides of the sash S are channeled vertically as shown at 1 for a purpose to appear.

Secured near the top and bottom of one of the channels 1 is a pair of supporting devices which comprise attaching plates 2 having ears 3 projecting outwardly from their opposite edges, said plates 2 being secured to the side bars of the sash by means of screws 4:. The ears 3 on one side of the plates 2 are provided with upright slits 5 while the ears on the other sides thereof are provided with circular bearing openings 6 which are disposed. inhorizontal alinement with the lower ends of the slots 5. Revolubly mounted: between the ears 3 and having their pintles 7 projecting into the slots 5 and bearing openings 6 are sash supporting rollers 8ywhich as shown, preferably have their peripheries of less length than their central. portions;

Located within; the channel 1 at the opposite side of the sash S, are upper and lower attaching plates 9 which have bearing ears l0, projecting outwardly from their opposite edges, said plates being rigidly secured: at 11 to the opposite ends of a fiat leaf-springlQ which is bent in such a manner. as; to provide a contact point 13 at its center, said point normally contacting with the edge of oneside bar of the sash. The cars; 10on one edge of the attaching plates 9 are provided with upright slots 14, while the ears on the other sides thereof have circularbearing openings15 which are disposed in. horizontal alinement with the lower ends off'said slots, said slotsand openings being providedfor the reception of bearing pintles 16 which project from the opposite ends of supporting rollers 17 which are located between said ears, and are adapted for a purpose to appear. For the purpose of retaining the spring 12 and the parts carried by the opposite ends thereof in proper position, I provide fastening screws 18 which project loosely through openings 19 near the opposite ends of said spring and enter the edge of the sash. It may here be stated that the rollers 8 and 17 are normally held in contact with the opposite inner sides of the frame E through the tension of the spring 12.

With the parts as above described, when the sash S is raised, the pintles of the various rollers will assume horizontal positions and will thus allow the sash to be readily, raised. When, however, the sash is released, its own weight will cause the ends of the pintles which are journaled in the bearing openings 6 and 15 to move downwardly, thus inclining said rollers and causing their direction of rotation to move the entire sash toward the parting strips P with which it will frictionally contact, thus retaining the sash in any one of its raised positions. The frictional contact between said sash and parting strips is not great enough, however, to prevent the sash from being lowered by force. Thus it will be seen that I have provided an extremely simple and eficient sash supporter which will retain the sash in any one of its raised positions, but which will allow said sash to be easily raised.

Although I have described my invention as applied to a window sash movable within the usual frame, it will be understood that I need not be limited to this applica-' tion, since the device would operate to equal advantage in connection with any fixed guide and movable member.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent is 2- l. The combination with a fixed guide and a movable member slidable against the same, of a roller carried by said member and in contact with said guide one end of said roller being mounted to move in a plane transverse to its axis.

2. The combination with a fixed guide and a movable member slidable against the same, of an attaching plate carried by said member, bearing ears on the opposite sides of said plate, one of the ears having a bearing slot and the other ear having a circular bearing opening, a roller having pintles mounted in said bearing slot and opening and means for causing said roller to contact with the guide.

3. The combination with a window frame having upright guide strips and a sash vertically movable between said strips and having its opposite edges channeled, of attaching plates within said channels, bearing ears on said plates, one of the ears on each plate having an upright siot and the remaining ears having circular bearing openings in horizontal alinement with the lower ends of said slots, and rollers between said ears and having pintles revolubly mounted in said slots and circular bearing openings, said rollers being in contact with said window frame, whereby the Weight of the sash, when raised will cant the rollers and cause said sash to friclionally contact with said upright strips.

4. The combination with a guide and a member movable in respect thereto, ot' a strip of spring metal having a contact point substantially at its center, attaching plates secured to the opposite ends of said strip, ears on the opposite sides of said attaching plates, one of said ears on each plate having a bearing slot and the remaining ears having circular bearing openings, rollers between said ears and having pintles projecting into said slcts and bearing openings, and retaining screws passing loosely through said metal strip and into said movable member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
